DigitalMaestro Posted July 8, 2018 Share Posted July 8, 2018 Hi, I am looking to build an unraid server and am testing functionality before making a purchase. I have an existing computer running Windows. My plan is to convert this computer to an unraid server and run the existing Windows install as a VM. However I have run across an issue. I would like to configure unraid while still keeping my existing Windows install active (since it is currently a media server for the home). To that end I bought a Mediasonic 4 bay eSATA dock with the intent to use this dock to hold the drives for the unraid array while I configure them. Once configured and confirmed working I could then move the drives into the system proper and boot the Windows install as a VM. My motherboard is an Asus P7H57D-V EVO with an eSATA port powered by a Marvell 88SE6111 (aka 88SE6121) chip. This chip supports the port multiplier function required by the aforementioned 4 bay dock. The dock works fine in Windows. If I install multiple drives in the dock then I can see all of the drives in the Windows disk manager so this confirms that the port multiplier feature is working correctly. However when I boot with unraid I only see one drive in the dock even if multiple drives are installed. Is there some special configuration needed to activate port multiplier support? This is critical for me as I need to be able to use the dock to configure unraid before moving the drives to the chassis so that I can preserve the ability to boot into Windows until everything is converted (no available SATA ports left on the motherboard that I can use for unraid hence the need for the 4 bay dock) Can someone please assist? Thanks in advance DM Quote Link to comment
